refocus on LLM mistakes, not textbook definitions

Based on actual review findings:
- Replay determinism: DateTime.utc_now() in apply, random in state
- Event design: OrderUpdated with changes map (CRUD-in-disguise)
- Projections as source of truth
- Suggesting event 'fixes' instead of compensating events
- Missing idempotency in handlers

Added Elixir/OTP specific patterns (handle_continue for replay,
Process dictionary for test isolation).

Anti-patterns table for quick flagging.

Initial DDD and event sourcing review patterns

Covers:
- Aggregate design (boundaries, invariants, identity)
- Event sourcing (immutability, naming, content)
- Domain vs integration events
- Eventual consistency
- Projections and read models
- Snapshotting (when and how)
- Process managers / sagas
- Value objects
- Common anti-patterns

Focus on subtle mistakes models make, not textbook definitions.
